Lee Jong Suk will finally return to the small screen with a new drama, "Big Mouse." The "While You Were Sleeping" star will be leading the series, along with YoonA.

Lee Jong Suk and YoonA will be playing the roles of a husband and wife whose lives will be ruined by a murder case. Almost two years after his absence, are fans ready for the model's return?

"Big Mouse," which is the drama's working title, will tell the story of a lawyer who will become a genius con artist named Big Mouse after getting involved in a murder case. From here, an intense turn of events will start to unfold.

Lee Jong Suk will be playing the role of Park Chang Ho, the lawyer who is about to uncover a deep conspiracy "surrounding the privileged class," AllKpop noted. He will do his best to survive while also trying to protect his family.

Sadly, Park Change Ho only has a 10% trial success rate. Also, as he often talks before acting, other lawyers have dubbed him the Big Mouth.

However, things will start to chance when he suddenly becomes the target after becoming the genius con artist that will put his life in danger. Alternatively, YoonA will play the role of Ko Mi Ho, a nurse and Park Chang Ho's wife.

She gives her full support to her husband to become a lawyer. But when she hears the news about his being a genius con artist, she will do everything to clear his name.

Elsewhere, news about YoonA joining Lee Jong Suk for a new drama emerged in May, Soompi noted. At the time, an industry representative revealed that the Girls' Generation member would be playing a married couple with Lee.

SM Entertainment, then, confirmed the news, saying its artist indeed received a casting offer for a new tvN drama and she was "positively reviewing the offer." "Big Mouse" would be YoonA's first drama after the end of "Hush" earlier this year.

Moreover, the new show will make Lee Jong Suk's return to the small screen after his mandatory enlistment in March 2019. His last known project was also a tvN series, "Romance is a Bonus Book."

Due to his ruptured ACL (anterior cruciate ligament) after a car accident when he was 16, the actor was deemed unfit for an active-duty soldier service, so he was instead put as a public service agent and discharged in January 2021.

Meanwhile, Jang Young Chul and Jung Kyung Soon will be "Big Mouse" creators, while Ha Ram will be the scriptwriter. Oh Choong Hwan will direct the series, which is set to be out in 2022.
